Drone can't arm

Hello, I have installed the Pixhawk firmware using QGC. Calibrated all sensors and everything. It arms perfectly when connected to the QGC via laptop MicroUSB cable. But when I disconnect the cable and try to arm it. It doesn’t arm the drone. Why is this and how to fix it. (Im using Pixhawk 6c, PM07 power module and Px4 firmware)

Do you have something like a SiK radio to see telemetry so that you see what is going on?

If not, I suggest that you set the param SDLOG_PROFILE so that it logs from boot. Then you try to arm and after it hasn’t worked you check the logfile. There should be some message in there telling you the reason why it could not arm.
